'NUT- LOCK.

SPECIFICATION forming part of Letters Patent No. 733,808, dated July 14, 1903 Application filed September 10, 1902. Serial No.'.122,872. (N0 model.)

To all whom" it may concern;

Be it known that I, JAMES G. BRANnom-a citizen of the United States, and a resident of Charleston, in the countyof Coles and State of Illinois, have invented certain new'and useful Improvements in Nut-Locks, of which the following is a specification.

This invention relates to nut-locks; andit has for its object to provide an inexpensive lock which may be quickly applied and removed from a nut and when applied will se-- curely lock the nut against movement.

With these and other objects, as will be hereinafter disclosed, the invention consists of the parts and the combinations of parts described in the following specification and pointed out in the claims. I p

In the drawingsforming a part of this speci-' fication, Figure 1 is aside view of a railroadrail joint having my invention applied thereto. Fig. 2 is a horizontal section'of the view shown in Fig. 1, and Fig. 3 is a perspective view of the lock detached from the rail.

\Vhile my invention may be used for locking nuts wherever employed, I have shown it in the attached drawings applied to a railroad-rail joint.

The two adjacent ends of the rail-sections 1 are connected together, as usual, by fish plates 2, bolts 3, passing through openings in the rail-sections 1 and fish-plates 2, and nuts 4. A plate 6 is provided, adapted to engage with the nuts 4 to prevent their turning. This is accomplished by providing the plate 6 with one or morenut-receiving open ings 7, which are elongated to permit the plate to be moved laterally. To hold the plate 6 to the object on which the nut or nuts are secured, the said plate is provided with a slot 8, having an enlarged portion 9. A headed stud 10, secured to the fish-plate 2, is fitted into the enlargement 9, and the plate 6 is then given a slight movement, so that the stud enters into the smaller portion of the slot 8, and the nut-lock is held to the nuts. A small play is allowed between the plate G'and fish-plate to permit the lock to be easily removed, said play being taken up by a fiat spring 11, secured at one end upon the inner side of the plate, extending longitudinally of the same and adapted to ride over a lug 11" on the fish-plate 2 to hold the .in place.

plate 6 against longitudinal movement. To look the plate against movement, one end of the plate 6 is bifurcated, as shown at 12, and between the bifurcation is mounted acam 13, having an operating-finger 14: and'bear- 1 iug against the spring 11.

The operation of the invention is as follows: The plate 6 is fitted to the rail so that the nuts 4 enter the elongated openings 7 and the headed stud 1O enters the enlarged por- The nut-lock is then 7 tion 9 of the slot 8. given a slight movement, so that the stud 10 enters the reduced portion of the slot 8 and the spring ll-drops behind the lug 11 on the fish-plate. The cam 13 is then turned by the finger 14, and the lock will be securely held Toremove the lock, the operation isreversed.

Various changes in form, proportion, and

minor details may be made within the scope of the appended claims without departing from'the spirit of my invention.

Having thus described myinvention, what I claim is 1. The combination with a plate having an elongated nut-receivin g opening to permit the 1 plate to slide while surrounding the nut, of

the object upon which the nut is secured, one

of said parts having a slot with an enlarged portion and the other of said parts having a fixed headed stud to fit within said slot, and a cam locking the plate against movement.

'2. In a nut-lock, the combination with a plate having nut-receiving openings and abifurcated end, of means holding the plate on the nut, anda cam mounted in the bifurcation and adapted to be turned to bear against the object secured by the nut to lock the plate against movement.

3. In a nut-lock, the combination with a plate having elongated nut-receiving openings to permit the plate to slide While surrounding the nut, and a slot having an enlarged portion, of a rigid headed stud carried by the object carrying the nut to fit within said slot, and a spring for taking up the play between the plate and the object carryingthe nut.

4. The combination with the plate, provided with an elongated'nut-receiving opening, a slot having an enlarged portion, and a bifurcated end; of a headed stud secured to the 6. The combination with a slidable plate having elongated nut-receiving openings, a flat spring upon the inner side of the plate, and a lug behind which the spring engages when the plate is slid to a certain position.

The foregoingspecifieation signed this 25th day of August, 1902.
